SHOE ATTACHMENT FOR BICYCLERS.

SPECIFICATION forming part of Letters Patent No. 388.9%9, dated September 4,1888.

Application filed May 4, 1888. Serial No. 272,840. (No model.)

To all whom it may concern.-

Be it known that l, Hnoroe M. CARTER, of Hyde Park, in the State of Massachusetts, have invented a new and useful Improvement in Bicyclcrs Shoe Attachments, of which the following, reference being had to the accompanying drawings, is a specification.

In the drawings, Figure 1 is a bottom plan of the attachment. Fig. 2 is a longitudinal vertical section showing the arrangement and connection of the same with the treadle of a bicycle, and Fig. 3 is a transverse section.

The treadle of bicycles usually consists of a pair of indiarubber cylinders swiveled upon the crank-pin of the bicycle-crank, and there is some difficulty experienced in getting an ad equately sufficient and steady hold of this treadle, except with shoes the soles of which are like the soles of tennis-shoes, soft and flexiblc, and so liable to insufficiently protect the feet of the rider. In order to furnish a proper protection for the foot and at the same time a good hold on the treadle, I have devised the thing which forms the subject of this application.

I make two plates, A and B, of metal, almost counterparts of each other, but differing in their exterior shape, according as they are designed to go upon the outside or inside of the foot, and according as they are right or left; but it is not absolutely necessary to make them rights and lofts, although a heater job and better fit could be obtained if they were so made. Each of these plates A and B is furnished with upwardly-projecting clamps a 1) upon its exterior, which clamps are adapted to engage with the sole of the riders boot or shoe. The plates AB may, if desired, be thickened somewhat at their center, as shown in Fig. 2, or they may be plain. These plates are linked togethcr near their back ends by the link f, which may be rigidly fastened to one of the plates and adjustahly fastened to the other plate, or may be adjustably fastened to both plates, if desired. The adjustment which I prefer is a screw-and-slot adjustment, the slot being made in the plate and the screw driven through the slot to take hold of the link. In order to keep the two plates A and B from moving endwise relative to each other, there should be either stops on the two sides of the link f, or two screws passing through the slot, and thus furnishing inside stops against end movements in a manner that will be familiar to most are chanics. At the toe end of the plate the plates 5 are brought together by means of the link 5/ and the cam-leverh. The link g is pivoted to the plate B adjustably, either by an arrangement which suffers it to be engaged with two or more pivot-holes in the plate B, or with a slot in said plate. The said link g is hitched at its free end to the lever lnwhich is pivoted at h to the plate A. The link 5 is separated from the surface of the plate B by a washer or boss a distance equal to the thickness of 6 the lever h at its pivot-hole, and the said link 9 is somewhat crooked at the end which engages with the plate B, as shown. The pivots g, which connect the linkg with the plate B, and the pivot g, which connects the 7 link 9 with the lever h, and the pivot 71/, which connects the lever h with the plate A, are not normally in the same line; but when the lever h is thrown around, so as to draw together the plates A and B, the pivot 9 passes 7 the center it, and a pin, h, or handle comesin contact with the edge of the link 9, and thereby prevents the lever it from moving any far ther, so that the passing of the joint between the lever h and the link 9 by the center 7i serves 8 to lock the apparatus without the aid of pins or other devices, although the lever h may be furnished with a pin on its top side, which may be engaged with a hole, b if such method of fastening is desirable. To these two plates A 8 and B there is pivoted a shield, G (l, which shield has a central block, 0, and two lateral flaps, d, the lateral flaps covering the links f g and lever h.

This device, it can readily be seen, can be 9 clamped upon the foot of a bicycle-rider, and the block 0 will engage between the two cylinders E of the treadle (shown in Fig. 1) and not be liable to slip endwise, which will be a great advantage to the rider. 9

The shield G d is to be made of indiaruhber, guttapercha, or other tolerably hard elastic material. Probably vulcanized iudia-rubber of the quality known as packing is best adapted for the purpose. I

I claim as inyinvention and desire to secure by Letters Patent of the United States- 1.
